The ProVane pump has self-adjusting vanes to eliminate efficiency-robbing slip, thereby allowing it to maintain near-original output and consistency, even after significant wear. Available in both ductile iron and stainless steel, its heavy-duty rotor and low shaft-stiffness ratio, combined with its hydrodynamic bearing design, result in extended bearing life, improved efficiency and energy consumption, better volumetric performance, and longer life. Five sizes, ranging from 3/4-in. to 2-in., are available, with operating speeds of 1,200, 1,800 and 3,600 rpm and capacities from 1 to 100 gal/min.
